problem with perl snips in xptemplate plugin

Hi,

Is anyone using xptemplate plugin? If yes anyone has problem with snips for perl filetype?

when I trigger any snippet defined for perl I get the below error

Error detected while processing function XPPprocess..5..<SNR>45_DoStart..<SNR>45_RenderSnippet..<SNR>45_NewRenderContext..XPT#classNew..<SNR>35_New:
E713: Cannot use empty key for Dictionary

I enabled verbose setting and tried to debug. But I find tracing problem is hard in vim(i'm not expert in vim script.

Note: For other file types i'm not having this problem. They are working fine.

PS: I see xptemplate google group is inactive and hence asking the question here?
